DESCRIPTION

49   XpmCreateXpmImageFromBuffer
50       To  create  an  XpmImage from an XPM buffer, use XpmCreateXpmImageFrom‐
51       Buffer().  The XpmCreateXpmImageFromBuffer() function reads  the  given
52       buffer to fill in the given XpmImage structure.  If the buffer does not
53       contain valid XPM data, it  returns  XpmFileInvalid.   If  insufficient
54       working  storage  is  allocated, it returns XpmNoMemory.  On success it
55       returns XpmSuccess.  If the passed XpmInfo  structure  pointer  is  not
56       NULL, XpmCreateXpmImageFromBuffer() looks for the following attributes:
57       XpmReturnComments  and  XpmReturnExtensions,  and  sets  possibly   the
58       XpmHotspot  attribute  when returning.  As specified in the table (page
59       28), if the data related to the attributes XpmReturnComments and XpmRe‐
60       turnExtensions  cannot be returned as requested because of insufficient
61       memory storage, XpmCreateXpmImageFromBuffer() will change the valuemask
62       to  mention  this and will try to continue.  So the caller should check
63       on this before accessing requested data.
64
65       Note: The valuemask of the passed XpmInfo structure must be set to some
66       valid value, at least zero, otherwise unpredictable errors can occur.
67
68
69   XpmCreateXpmImageFromData
70       To  create  an  XpmImage  from  an XPM data, use XpmCreateXpmImageFrom‐
71       Data().  XpmCreateXpmImageFromData() fills in the given XpmImage struc‐
72       ture  from the given data. If the data does not contain valid XPM data,
73       it returns XpmFileInvalid.  If insufficient working  storage  is  allo‐
74       cated,  it  returns XpmNoMemory.  On success it returns XpmSuccess.  If
75       the passed XpmInfo structure pointer is  not  NULL,  XpmCreateXpmImage‐
76       FromData() looks for the following attributes: XpmReturnExtensions, and
77       sets possibly the XpmHotspot attribute when returning.  As specified in
78       the  table (page 28), if the data related to the attribute XpmReturnEx‐
79       tensions cannot be returned as requested because of insufficient memory
80       storage,  XpmCreateXpmImageFromData() will change the valuemask to men‐
81       tion this and will try to continue.  So the caller should check on this
82       before accessing requested data.
83
84       Note: The valuemask of the passed XpmInfo structure must be set to some
85       valid value, at least zero, otherwise unpredictable errors can occur.
86
87
88   XpmCreateXpmImageFromImage
89       To create an XpmImage from an XImage, use XpmCreateXpmImageFromImage().
90       From  the given X images and XpmAttributes if not NULL, XpmCreateXpmIm‐
91       ageFromImage() creates an XpmImage  following  the  same  mechanism  as
92       XpmWriteFileFromImage(3).
93
94
95   XpmCreateXpmImageFromPixmap
96       To create an XpmImage from a Pixmap, use XpmCreateXpmImageFromPixmap().
97       From the given pixmaps and XpmAttributes if not  NULL,  XpmCreateXpmIm‐
98       ageFromPixmap()  gets the related XImages by calling XGetImage, then it
99       gives them to XpmCreateXpmImageFromImage() to create an XpmImage  which
100       is  returned to xpmimage.  Finally it destroys the created X images us‐
101       ing XDestroyImage(3).
